SPRING-WIRE MATTRESS.

SPECIFICATION forming part of Letters Patent No. 618,386, dated January24, 1899,

Application filed January 17,1898. Serial No. 666,961. (No model.)

a citizen of the United States, residing at Chicage, in the county ofCook and State of Illi- .Fig. 2.

nois, have invented certain new and useful Improvements in Spring-WireMattresses,'of which the following is a specification.

My invention relates to improvements in spiral-spring mattresses; andits object is to provide a series of links for bracing and securing theends of the springs that may be readily and easily applied. I attainthis object by the mechanism illustrated in the accompanying drawings,in which Figure 1 is a perspective of the link with a section of theupper circle of a spring in position to show the manner in which thelink is applied to brace the coil laterally; and Fig. 2 is a plan ofportions of disconnected springs, showing the manner of connecting themwith the links.

Similar letters refer to similar parts throughout the several views.

The link which I'have adapted for the purpose set forth consists of asingle wire having two short bows or bends a a proper distance apart andof a proper depth to receive the two opposite sides of the top or bottomY coil of the spring and allow the body A of the link to project a shortdistance above or below, as the case may be, the coil that it supports.At each end of these links I form a bend a in opposite directions and atright angles with the bends a and in position to pass over the top ofthe coil that lies in said bends and around said bends, thence back overand around the coil, as shown at a in The relative position of the linkand the bow in the center of the link is more plainly illustrated uponthe partial coils B in Fig. 2, where the bends a are shown in sectionaround the coil and the end of the link in the position it is placedbefore being wound around the coil. WVith this arrangement it isimpossible for the link to slide upon the coil and allow the coil todrop over out of place, or one coil to incline in one direction and theother in the opposite direction, or for the upper coil of the spring tospread and slide out of position on the link, and it tends to greatlyincrease the elasticity of the springs, as they have the benefit of theelasticity of the links, while with the ordinary link such elasticity isnot secured.

' Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent of theUnited States, is

In combination with the vertical coiled springs of a spring-wiremattress, a series of tie-links, each formed of a single piece of Wirehaving depressions in its body for the reception of the opposite sidesof the end coil of a spring,and having its end or ends bent in U form topass over the coil of the next'adjacent spring and around the bend in,and

under the body of, the next adjacent link in which the coil of said nextadjacent spring lies, thence back, hooking over this coil, to form afirm connection between the coils, substantially as and for the purposeset forth.
